Connecting tube is installed, the end of connecting tube is movably installed with injection needle, defining flange, defining flange are provided on the casing
It is provided with supporting block on the casing of side, adjusting gag lever post is slidably fitted in supporting block, adjusts one end and the limit of gag lever post
The push handle of the connection of flange Intermittent Contact, the other end and piston rod that adjust gag lever post connects.
The provided circumferentially about of adjusting gag lever post has external screw thread, and connecting hole is provided in push handle, is arranged on connecting hole
There is internal screw thread, adjusts and connected between gag lever post and connecting hole by the matching thread of external screw thread and internal screw thread.
The ellipsoidal cross section of the adjusting gag lever post, adjusts and is provided with adjusting rod quarter in the plane of the two sides of gag lever post
Angle value.
The casing and connecting tube is made of clear material respectively, and casing scale value is provided on casing.
Utility model has the advantages that
The simple insect microinjection apparatus structure is simple, and practicability is good, in the course of work, by adjusting gag lever post and limit
The cooperation of position block, can effectively ensure that accurately injection volume, so that per injection can be accurate to same volume, avoids existing note
The error being artificially difficult to control when penetrating；It is used especially suitable for insect micro-injection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the adjusting gag lever post of the utility model；
Fig. 3 is the schematic cross-section of the adjusting gag lever post of the utility model.
In figure: 1, injection needle, 2, connecting tube, 3, casing, 4, piston rod, 5, injection nozzle, 6, defining flange, 7, supporting block,
8, gag lever post, 9, push handle, 10, adjusting rod scale value, 11, casing scale value are adjusted.
Specific embodiment
The simple insect microinjection apparatus it be made of injection needle 1, connecting tube 2 and syringe；Syringe is by 3 He of casing
Piston rod 4 is constituted, and one end of piston rod 4 is inserted into casing 3, and 3 front end of casing of syringe is movably installed with by injection nozzle 5
Connecting tube 2, the end of connecting tube 2 are movably installed with injection needle 1, and the purpose of connecting tube 2 is to extend the injection of medical fluid in injection
Process, to facilitate the control of injection volume.
Defining flange 6 is provided on the casing 3 of the simple insect microinjection apparatus, on the casing 3 of 6 side of defining flange
It is provided with supporting block 7, is slidably fitted in supporting block 7 and adjusts gag lever post 8, adjusts 6 interval of one end and defining flange of gag lever post 8
It connects.
It is provided with connecting hole in the push handle 9 of the piston rod 4 of the simple insect microinjection apparatus, is provided on connecting hole interior
Screw thread, adjusting the provided circumferentially about of gag lever post 8 has external screw thread, adjusts and passes through outer spiral shell between the other end and connecting hole of gag lever post 8
Line is connected with the matching thread of internal screw thread.
The ellipsoidal cross section of the adjusting gag lever post 8 of the simple insect microinjection apparatus, adjusts the two sides of gag lever post 8
Adjusting rod scale value 10 is provided in plane, pushing away for piston rod 4 can be set by rotating adjusting gag lever post 8 by adjusting rod scale value 10
Progress with accurate propelling piston bar 4, and then is precisely controlled injection volume.
The casing 3 and connecting tube 2 of the simple insect microinjection apparatus are made of clear material respectively, with side at work
Just it observes, casing scale value 11 is provided on casing 3, to control the extraction and storage of medical fluid.
When the simple insect microinjection apparatus works, it is first depending on casing scale value 11 and extracts the medical fluid of required injection
It stores to casing 3, then adjusts the injection volume for adjusting gag lever post 8 to control single polypide according to adjusting rod scale value 10, with
The insect benumbed is placed under insect anatomy mirror afterwards, polypide is carefully fixed with the tweezers of flat mouth, then slowly pierces injection needle 1
Enter insect body, it is above-mentioned be ready to complete after, slowly push the push handle 9 of piston rod 4, medical fluid be slowly injected into insect body and is accused
Complete injection.During this, due to setting the advance distance of piston rod 4 by adjusting gag lever post 8 in advance, work as adjusting
When gag lever post 8 and defining flange 6 contact, piston rod 4 can not continue to move ahead, and be achieved in the purpose for being precisely controlled injection volume.
Polypide is placed in cut-and-dried culture dish after having injected, after insect replys activity, insect is gone into feeding worm
In device.It is every injected an insect after, by injection device with washes of absolute alcohol one time, then injected next time.With
This can carry out continuous injection infinitely repeatedly.
